Abstract
The proportional navigation guidance law with gravity over compensation was studied to increase the impact angle. The gravity compensation, as an additional acceleration command, was introduced to the guidance loop. The mathematical model of the proportional navigation guidance system with gravity over compensation was established. The effects of gravity compensation coefficient and proportional navigation coefficient on the guidance system were analyzed. According to the telemetry data, the gravity compensation coefficient and proportional navigation coefficient were identified, which validate the theoretic design results. A universal method for design the proportional navigation guidance system with gravity over compensation to improve impact angle was obtained.
